Ventilation Control - AERMEC GLF10N Manual De Uso E Instalación

VENTILATION CONTROL

Thermostat-controlled ventilation: The
choice of the regulation according to ther-
mostatically controlled ventilation (dip3
OFF) foresees the switching off of the ven-
tilation when the setpoint is reached. (See
the dip switch settings table).
Continuous ventilation: The continuous
ventilation is selected by means of dip3
that must be set to On. In practice the
continuous ventilation provides ventila-
tion even with thermostat fulfilled at the
speed chosen. This function is disabled if
Position
The thermostat is off. It may however start again in Heating mode if the room temperature falls below
OFF
7°C and the water temperature is suitable (anti-freeze function).
AUTO On reaching the setpoint, the ventilation proceedes with the minimum continuous speed.
In this position, the minimum ventilation speed V1 is always active regardless of thermostat
V1
requirements.
In this position, the average ventilation speed V2 is always active regardless of thermostat
V2
requirements.
In this position, the maximum ventilation speed V3 is always active regardless of thermostat
V3
requirements.
In this position, the minimum Aux ventilation speed is always
Aux
active.
VALVE OPERATION
If a shut-off valve is present (dip1 ON),
the position of the probe can be man-
aged both upstream and downstream of
the valve itself (in the standard position
on the heat exchanger). The main differ-
ence between the two is in managing the
ventilation in different ways. If the water
probe is upstream of the valve (dip2
ON) or is not present, a heat exchanger
pre-heating function occurs and ena-
bles the fan 2'40" after the first opening
of the valve.
The valve in question (for the heat
exchanger pre-heating function) is Y1 if
this is a 2-pipe system (dip5 Off), whereas
if it is a 4-pipe system it is Y2 (dip5 On).
the machine has no shut-off valve (dip1
OFF). In these particular cases, the ventila-
tion will always be managed with thermo-
statically controlled logic.
The following table shows the ventilation
speed activated depending on the posi-
tion of the selector:
Operations
The inhibition time of the fan is then auto-
matically calculated and depends on how
long the valve remains closed; in this way
it could vary from a minimum of 0' 00"
to a maximum of 2' 40". This ventilation
enabling delay in relation to the opening
of the valve is reset if the electric resistor
is enabled, this is to ensure greater user
safety.
Refer to the specific table for the specific
parameters of the dip switches.
